Can I use coconut oil on keratin-treated hair? Yes, but at the right time

  • If you got a keratin treatment less than two weeks ago, using coconut oil is not a good idea. Your hair is already repaired, nourished, and moisturized.
  • Also, since it takes 15 days for the keratin to settle inside the hair fully, your hair won’t be able to absorb the oil, and it will go very greasy.
  • Of course, you could use a clarifying shampoo to completely remove the coconut oil. But by removing the coconut oil, you would also be removing some of the keratin.
  • Once you get a keratin treatment, waiting two weeks to use coconut oil is ideal. And later I’ll tell you how to use it correctly.

Don’t think I don’t understand you.

You’ve got that keratin treatment, and you see your hair is so healthy, docile, and soft that you feel that if you don’t keep applying things to your hair, the effects of the treatment will magically disappear overnight.

But things don’t work like that.


 If you’ve just got a keratin treatment in your hair, what do you want to use coconut oil for?

The keratin starts repairing your hair from the very moment you get the treatment. And it continues to settle in the hair for another two weeks.

That’s why I always recommend my clients reactivate the keratin once a week after washing their hair by using a blow dryer.

 If it’s been less than fourteen days since you got the keratin treatment, you shouldn’t use coconut oil, and all you have to do is simply enjoy your healthy hair. 


To tell you the truth, you should enjoy it while you take extra care of it. For instance, wash your hair less often and use shampoos and conditioners without sulfates.


Because if it’s been less than fourteen days since you got the keratin treatment, your hair doesn’t need the nutrients provided by coconut oil. For the simple reason that the keratin has already provided all the nourishment your hair needs.

 If it’s less than two weeks since you got the keratin treatment and you use coconut oil , you will saturate the hair cuticles. Then your hair will most likely become so greasy that you’ll need to wash it with a clarifying shampoo, which will remove both the oil and some of the keratin treatment.

And this brings us to the following.

How to use coconut oil two weeks after getting a keratin treatment

 The important thing is “how” you use the coconut oil two weeks after getting the keratin treatment. 


Remember that the keratin already repaired your hair, so you should “measure” the use of coconut oil.

  •  If you straighten your hair to reactivate the keratin treatment, you can use coconut oil as a thermal protector.  In this case, it’s essential you apply the oil on wet hair and wait for it to dry. Only when your hair is completely dry use the straightener.
  •  If you notice some frizz starting to appear , you can put a few drops of coconut oil in the palms of your hands, rub them together and run the oil through your frizzy strands.
  •  You can also apply coconut oil as a mask, but only on the ends.  Leave it on for twenty minutes and after the exposure time, wash your hair with a sulfate-free shampoo.


But  it’s super important you DON’T use coconut oil by leaving it on overnight or for hours all over your hair.  Otherwise, you will overload your hair and look dull, heavy, and greasy.



You can use coconut oil two weeks after getting a keratin treatment. However, you should use it with caution. For example, use it as a heat protector before straightening your hair. Or use it as a twenty-minute mask, just on the ends.
